Abstract (en)

[origin: WO9830522A1] Arylolefinic compounds are prepared by reacting aryl halide with an olefinic compound in the presence of a polar liquid reaction medium containing (a) secondary or tertiary amine as a hydrogen halide acceptor, (b) a catalyst system formed from (i) Pd or Pd(0) compound, and/or Pd(I) salt or Pd(II) salt, and (ii) a tertiary phosphine ligand, and (c) a reaction accelerating amount of water in the range of 0.5 to 5 weight percent of the total weight of the reaction mixture. The arylolefinic compounds can be converted to an arylcarboxylic acid by hydrocarboxylation with CO in a reaction medium freed of amine and containing water and a Pd catalyst system as above in which a copper component may be included, and which preferably includes an ether such as THF.
